MACHINE FOR AERATIN-G LIQUIDS AND BOTT LING SAME.

SPEGIFIGATIGN forming part of Letters Patent No. 727,710, dated May 12,1903. Application filed May 15, 1902. Serial No. 107.477. (No i nodal.)

To a whom it may concern.-

Be it known that I, TOMSUTOLIFFE, a subresiding at 18 Allerton road, Stoke Newington, London, England, have invented a new and useful Machine for Aerating Liquids and Bottling Same, of which the following is a specification.

This invention relates to machines for aerating or carbouating liquids and for filling bottles, jars, or othervcssels therewith, and especially relates to that class of aerating or carbonating and filling machines which are operated by a crank-wheel or equivalent hand-operated means.

The object of my inventionis to simplify the construction of such machines and also to obviate the necessityof the person operating the machine having to overcome the full pressure of the carbonic-acid gas employed for carbonating the liquid when pumping liquid into the mixing-chamber, thereby rendering the operation of my improved machine easier and (as compared with such machines hitherto in use) enabling alarger quantity of liquid to be aerated or carbonated and a greater number of bottles or other vessels to 7 be filled with the same amount of work expended by such operator.

In order that my invention may be readily understood, I make reference to the accompanying drawings, wherein- Figure 1 is a front elevation; Fig.2 a side elevation of a machine constructed in accordance with my invention, and Fig. 3 shows the cams on the main spindle for operating various parts of the machine.

In carrying my invention into practice I employ a suitable standard at, fixed on abase 5 and provided at its upper end with 'bearings in which a spindle 6 is carried, on one end of which is fixed a crank-wheel 7, having 1 a handle 8,.and on the other end a crank 9,

Y of any usual construction.

Within the mixin -chamber I provide an agitator 13, which consists of plates or sections of plates and which is fixed to and moved with the pump-rod 14., the latter being connected to the crank-pin 10 by a forked connecting-rod 15,and by reason of said crankpin being adjustable on its crank the stroke of the pump and that of the agitator can be regulated. The carbonic-acid gas is contained in the usual cylinder, from which it passes through a pressure-reducing valve and tube 41 into the mixing-chamber. I do not confine myself to any particular method of introducing the gas into the mixing-chamber; but byway o'fexample I may employ a tube leading direct from the reducing-valve to said chamber, said tube being at its outlet provided with a rose or equivalent, so as cause the gas to intermingle with the liquid, which latter is derived from a suitable reservoir and is forced into the mixing-chamber by the pump,the liquid-inlet being at the top of said chamber and said liquid being preferably, also, forced through a rose, so as to intermingle it with the gas.

. From the bottomof the mixing-chamber a pipe 16 leads to the usual filling-head. 17, adapted to receive the mouth or equivalent of a bottle, siphon, or other vessel, which bottle or other vessel rests on the ordinary adjustable rest 18, which is normally pressed upward by a springin the usual manner, so as to cause a tight joint to be made between the bottle-mouth and the head when said bottle is being filled. Said rest is carried by a rocking lever 19, which is operated by a cam on the spindle 6, as hereinafter described, the arrangement of the parts being such that by turning the wheel 7 the pump forces liquid through a pipe 42 into the mixing-chamber, and gas is simultaneously also admitted through the pipe 41 to said chamber. When sufficient liquid has been pumped thereinto, which can be seen from a water-gage20, (the mixing-chamber should be about half-full,) it will be ready to be drawn offinto bottles or other vessels, said liquid having been thoroughly aerated or carbonated by the action of the agitator, which, as already stated, is worked simultaneously with the pump".

The mixing-chamber is provided with the usual safety-valve 21, and the pipe 16 is provided with a cook or tap 22, which is turned on when a bottle orother vessel is being filled, said.tap being operated either by hand or by a lever receiving its motion from a cam on the spindle 6 or otherwise.

The crank 9 is preferably formed with a slot, along which the crank-pin 10 may be adjusted and fixed in any desired position, and along said slot I mark a scale, so that I may adjust said crank-pin in accordance with said scale, and each stroke of the pump will force a certain thus predetermined quantity of liquid into the mixing-chamber. The crankpin is adjusted so that the pump at each stroke forces an exactly equal quantity of liquid into the mixing-chamber to that drawn off in filling the bottle or other vessel, and if the latter be small the stroke both of the pump and the agitator will be correspondingly short, as each will only be worked to the extent necessary.

Fig. 3 shows the arrangement of cams for operating the usual syrup or essence pump 23, the bottle-rest 1S, and the valve or tap 22. For operating the syrup-pump I provide a cam 2 which lifts the syrup-pump rod 25, the latter being provided with a roller 26, which rolls on the cam. In order that the cam 24 will depress the pump-piston, I connect a vertical rod 27 to the pump-rod 25, on which I mount a roller 28, so that when the spindle 6, and with it the cam 24, has been rotated ahalf-revolution the said cam will depress the roller 28, and with it the rod 27, the pump-rod 25, and the syrup-pump piston.

For operating the bottle-rest I provide a cam 29, which actuates a lever 30, which is pivotally connected to the bottle-rest frame 31. A link 32 connects said lever 30 and the rocking lever 19 together, said rocking lever operating the vertical rod 34 of the bottlerest 18.

For the purpose of operating the valve or cook 22 I provide a cam 35, which operates a rod 36, which is guided in a guide 37 and is provided with a roller 38, the top end of the rod 36 being pivotally connected to the valve or cook operating lever 39.

The main advantage derived from placing the pump so that its rod operates the agitator is that when forcing the liquid into the mixing-chamber the resistance to be overcome is not the force of the gas-pressure on the whole area of the pump piston or bucket, but only on that area less the area of the pump-rod, which latter may be made of any desired diameter. I am aware that on the downstroke of the pump when the latter is drawing liquid into its cylinder the resistance to be overcome is increased by the pressure of the gas acting on the pump-rod; but it is preferable to increase the resistance to some extent on the downstroke if the resistance on the upstroke is decreased by a corresponding amount, as by this means the resistance to be overcome can be arranged to be fairly constant instead of being almost ml at one part of the stroke and excessive at another. A further advantage appertaining to my im proved machine is that a single crank operates both the pump and the agitator, so that not only is friction reduced in working, but the machine is much more simple in construction, is cheaper to make, and occupies less space than those hitherto in use.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. In a machine foraeratingor carbonating liquids, a mixing or carbonating chamber, a pump situated in alinement with said chamber, a piston or pump rod of sufficient length to extend thereinto, an agitator within said chamber carried by the pump-rod, and a forked connecting-rod connecting the pump rod to a crank, all for the purposes and substantially as set forth.

2. In a machine foraerating or carbonating liquids, the combination of a standard 4 fixed on a base 5, hearings on said standard, a spindle 6 carried in said bearings, a crank-wheel 7 fixed at one end of said spindle, a crank 9 formed with a slot and having a scale marked thereon fixed to the other end of said spindle, a crank-pin 1O adjustable in said slot, a pump 12, a mixing-chamber 11, the pumprod 14 entering said mixing-chamber, and an agitator fixed to said pump-rod, all for the purposes and substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
